TOKEN RING
ISOLATION TRANSFORMERS
Designed for 4 and 16 Mbps Applications
Application Notes for Surface Mount:
These transformers are designed for use in Token
Ring applications that support both 4 Mbps and
16 Mbps data rates. The varying turns ratios allow for
maximum design flexibility in either DTE or MAU
applications.
For information on combined filter and transformer
modules that support either IBM and National
Semiconductor, or Texas Instruments Token Ring
chip sets, contact Pulse today.
